"Everyone thought, like back in the '80s, '90s, everyone started noticing, scientists started noticing that people who naturally had people with lower amounts of vitamin D in their blood had higher rates of all like the classic chronic diseases. So they started recommending vitamin D pills. So then they did all these clinical trials to prove that it would help. Huge, huge clinical trials, tens of thousands of people, follow-ups that went for many years. None of them showed a benefit."
Despite observational data linking natural vitamin D levels to lower disease rates, massive clinical trials of vitamin D supplementation showed zero benefit for any condition. The New England Journal of Medicine published an editorial in 2022 recommending doctors stop prescribing it. Natural vitamin D from sun exposure, however, correlates strongly with reduced mortality.
